WAGON-BODY LIFTER.

SPECIFICATION forming part of Letters Patent No. 711,337, dated October14, 1902.

Application filed January 10,1902. Serial No. 89,166. (No model- To allw/wm, it may concern.-

Be it known thatLOHARLEs XV. NAIBB,a citizen of the United States,residing at Charleston, in the county of Mississippi and State ofMissouri, have made certain new and useful Improvements in Wagon-BodyLifters, of which the following is a specification.

My invention is an improvement in wagonbody lifters, and has for anobject to provide simple novel constructions whereby to lift thewagon-body and subsequently to lift the running-gear; and the inventionconsists in certain novel constructions and combinations of parts, aswill be hereinafter described and claimed.

In the drawings, Figure l is a side elevation of my invention ready foroperation to lift the wagon-body. Fig. 2 is a similar view showing thewagon-body lifted. Fig. 3 is 'a rear View of the apparatus with theparts in the position shown in Fig. 2. Fig. 4 is a side elevation of thedevices for lifting the running-gear, showing the latter lifted. Fig. 5is a top plan view-of the devices for lifting the running-gear, andFigs. 6 and 7 are detail perspective views.

In carrying out my invention I prefer to provide the several devices insuch form and arrangement that most all of them can be made by a farmerfrom the timber at hand, thus avoiding the expense and inconvenience ofsecuring dressed timber.

In order to guide the wagon into position for operation by the parts ofthe apparatus,

I employ guide-rails A, which may be laid upon the ground or othersuitable support and are of such gage as to guide the wagon accuratelyto position for operation by the lifting devices.

The wagon-body lifter comprises a liftingframe composed of uprights Band B, which are pivoted at their lower ends at b and b and areconnectedat their upper ends by the beams 0, these top beams 0 being arranged toconnect the uprights B and B at the opposite sides of the lifter, andthe opposite uprights B being connected by cross-beams D, and theuprights B being connected by the crossbeams E, as will be understoodfrom Figs. 2 and 3. By the beams B and D and the beams B and E, Iprovide front and rear frames connected by the top beams O to form acomplete lifting-frame, which will operate after the fashion of aparallel ruler, as will be understood from Figs. 1 and 2.

Slings F and G are suspended from the lifting-frame and adapted to beapplied beneath the wagon-body at the ends thereof, as shown in Figs. 1,2, and 3, to lift said body when the lifting-frame is adjusted from theposition shown in Fig. 1 to that shown in Figs. 2 and 3 and indicated indotted lines in Fig. 1. In operation the wagon is driven beneath thelifting-frame, as shown in Fig. 1, and a line H, secured to thelifting-frame at about the juncture of the beams 13 and O, is connectedwith one of the front standards of the wagon,- as shown at I in Figs. 1and 2, and the Wagon is then moved forward and will operate to adjustthe lifting-frame fromthe position shown in Fig. 1 to that shown in Fig.2, thus lifting the wagon body to the position shown in Figs. 2 and 3.When adjusted to this position, the lifting frame will be held by meansof the locking bars J, which are pivoted at their lower ends and rideupon laterally-extending studs K, carried by the lifting-frame. Theselocking-bars J, of which I use one at each side, are provided at J andat J with notches to receive thestuds K, the notch J being in positionto receive the stud K to support the lifting-frame in the position shownin Fig. 1 and the notch J supporting said liftingframe in elevatedposition, as shown in Fig. 2 and indicated in dotted lines in Fig. 1. Itwill be noticed that the notches J are sloped on their upper sides, sothe lifting-frame can be elevated from the full-line position shown inFig. l to the position indicated in dotted lines in said figure. Torelease the locking-bar from engagement with the stud K when the partsare in the position shown in Fig. 2, I provide a rock-shaft L, providedat its ends with lever-arms M, one of the ends of which is connected byropesM with the locking-bars J, while their other arms are suppliedwith-ropes M leading to the ground, so the lock-bars can be released topermit the adjustment of the lifting-frame from the position shown inFig. 2 to that shown in Fig. 1. It will be noticed that this releasingmechanism is carried by the lifting-frame and is arranged for operationfrom the ground and enables the operator to easily release thelifting-frame, so it can be lowered to the position shown in Fig. 1, inwhich it will be supported by the locking-bars, as shown. When therunning-gear has been moved to the position shown in Fig. 2, it overliesthe lifting mechanism for the said running-gear, the construction ofwhich is best shown in Figs. 3, 4, and 5, and includes end frames N andO, which are pivoted at N and O, are connected at their upper ends bytop beams P, and have cross-bars N and 0 a brace-sill N being providedfor engagement by the locking-bar Q, which is pivoted at Q and isnotched at Q to engage the brace-sill or other abutment, as will beunderstood from Figs. 4 and 5. In operation the parts N, O, and Pconstitute a liftingframe, which may be adjusted from the positionindicated in dotted lines in Fig. 4 to that indicated in full lines insaid figure by means of a line R, secured to the running-gear, so thelatter as it is moved forward from the position indicated in dottedlines, Fig. 4, to that indicated in full lines in said figure willadjust the lifting-frame to the full-lineposition in Fig.4,whereinitwill be secured by the lockingbar Q. For releasing the saidlocking-bar I provide a rocking device or shaft S, journaled to the topbars of the lifting-frame and having a crank-arm R, by which it may berocked, and affording at R a drum-like surface to receive a rope R bywhich it is connected with the locking-bar Q, so the shaft S may whenturned operate to release the locking-bar. It will thus be noticed thatin Figs. 3, 4, and 5 I illustrate a lifting-frame for use in connectionwith wagons, which lifting-frame is similar to that for lifting the bodyand before described to the extent that it includes, in connection witha lifting-frame adapted to operate after the fashion of a parallelruler, a locking-bar for securing the lifting -frame when elevated andmeans for releasing said locking-bar including a rock-shaft carried bythe lifting-frame and connected with the locking-bar and arranged whenturned to release the. said bar to permit the lifting-frame to lower. Itwill also be noticed that the bodylift-ing frame and therunning-gear-lifting frame are so located, with the body-lifting framelying above the lifting-frame for the running-gear, that therunninggear-lifting frame is arranged to operate upon the running-gearsubsequent to the lifting of the wagon-body and by the movement of saidgear beyond the position to which it is moved for lifting the body.

In practice it is preferred to incline the uprights B and B inwardlytoward each other at their upper ends, as shown in Fig. 3, so they willbrace each other, and there will be no tendency of the said uprights toswing out of position for use.

As before suggested, the construction is simple and can be readilyconstructed by a farmer or teamster from the material at hand.

Having thus described my invention, what Iclaim as new, and desire tosecure by Letters Patent, is

1. The combination of the lifting-frame, a locking-bar'snpportedindependently of said frame and arranged to secure the same in elevatedposition, and devices whereby the locking-bar may be released fromengagement with the lifting-frame, the lifting-frame being adapted toextend over and support a wagon-body, substantially as set forth.

2. The combination with the lifting-frame having pivoted upright barsand top bars connecting the same, of the locking-bars supportedindependently of the lifting frame arranged to engage the liftingframeand secure the same when elevated, a rock-shaft journaled to the topbars of the lifting-frame and having lever-arms, connections between oneof said lever-arms and the lifting-bars whereby to release the same,substantially as set forth.

3. The combination in an apparatus substantially as described, of thelifting-frame arranged to be elevated by the movement of the vehicle,and a frame for lifting the running-gear and over which the running-gearmay be moved to adjust saidframe to elevated position, substantially asset forth.

4. The combination of the body-lifting frame having front and rearuprights, and cross-bars connecting the same, the lockingbars by whichto secure the said lifting-frame in elevated position, a rock-shaftjournaled to the lifting-frame and having crank-arms and cordsconnecting the same with the locking-bars and cords connected with thecrankarms of said rock-shaft and arranged for operation, substantiallyas described.

5. The combination in a wagon-body lifter, of the lifting-frame havingfront and rear frames and top bars connecting the same, slings carriedby said front and rear frames for supporting the opposite ends of thewagonbody whereby the said body may be suspended within thelifting-frame, and means for locking the lifting-frame when elevated,substantially as set forth.
